Mood Board supports several types of masking for items that have been added to Mood Board documents. Each of the masking options is available by opening the metadata panel Edit: Edit Metadata (Command+E) under the “Masking” group in the popover panel.

• Oval
  Oval masks use the aspect ratio of the asset selected to create a pinhole effect. Only the “Inset” slider is used for masks of this type.
• Square
  Square masks use the aspect ratio of the asset selected to create a cropping effect. Inset and Rounding are both used to create the final mask effect.
• Diamond
  Diamond masks create a parallelogram based on the aspect ratio of the selected asset. Only the “Inset” slider is used for masks of this type.
